FRANK SCELZA', OF HARRISGN, NEW YORK.

DOOR-JAMIE SETTER.

To all whom it may concern:

Be it known that I, FRANK ScELzA, a subject of the King of Italy,residing in Harrison, in the county of VVestchester and State of NewYork, have invented certain new and useful Improvements in Door JambSetters, of which the following is a specification.

My invention relates to devices for setting door-jambs, and particularlyto an attachment to such devices whereby the mortise of the door hingemay be located in position and cut by means of guides which insure thecorrect cutting of the mortise.

My invention consists in gages adjustable upon the door frame for thepurpose of locating the position of the said mortise, and adjustableguides carried by the said gages for guiding tools employed to cut themortise.

One practicable manner of employing my said invention is illustrated inthe accompanying drawings, wherein Figure 1 is a plan view of adoor-jamb setting frame illustrating my invention applied thereto. Fig.2 is a cross-section on the line 22 of Fig. 1. Fig. 3 is an enlargedface view of parts of the frame illustrating the tool-guiding means forcutting the depth of the mortise. Fig. 4 is a view similar to Fig. 8,the parts of the frame there shown being omitted, and illustratingtool-guiding means for cutting the width of the mortise. Fig. 5 is aview of part of the frame. Fig. 6 is a cross-section on the line 6-6 ofFig. 5; and Fig. 7 is a detail section on the line 77 Fig. 4.

My invention may be employed in connection with any suitable door-jambsetting frame. As illustrated it is applied to such a frame, which Iwill designate as a whole by the letter A, which has relatively adjustable parts. Said frame is composed of uprights a a, each of which isof two pieces relatively adjustable or extensible through a tongue ahaving beveled edges which are received in an undercut groove a of theopposite part of the upright, as seen in Fig. 6. A set screw (4*, holdsthe two parts of the upright when adjusted in position. Upright a issimilarly equipped with tongue, groove and set screw. These uprights areconnected by cross-braces a a which are also extensible, and aresimilarly provided with tongues and grooves and set screws to permitsuch extension. Said frame is Specification of Letters Patent.

equipped with levels a a for plumbing the frame.

As convenient means for holding the hinge-setting devices I mayconstruct chan' nels a upon the outer sides of the uprights a a Thesechannels are located at about the position the hinge will come and areof sutlicient size to provide a reasonable margin for the location ofsuch hinges. Within these channels where they are employed 1 locate thedevices for determining the position of the hinges and for guiding thetools in cutting the mortise. These devices constitute my invention. Asshown the said devices comprise gages B of which I prefer to-employ apair for each hinge, and as the gages in each pair are similar inconstruction I will describe one of them. Each gage B is adjustable upand down or lengthwise of the frame A, and relatively to its mate andhas means provided for the purpose of permitting such adjustment and ofsecuring the gage in position in said frame, which as illustratedcomprise a tongue Z2 which enters an undercut groove 6 in the frame,whereby the gage is held in position and is permitted to slide up anddown in said groove. A set screw 6 may be provided to retain the gage inadjusted position. The gage is preferably equipped with an arm 7) which.is arranged parallel with the face of the frame, and serves to embracethe end of the doorjamb C. This arm on its outer face has an undercutgroove 5* within which slides a block 6 A set screw b passes through aslot 6 in said slide, serving to hold it in position. Upon this slide ismounted a pin .71 and a tool guide 6 is slotted at 7) I), and the saidslots receive upper and lower pins 5 The inner horizontal edges of thearms 72 as shown may be beveled atthe top to allow the chisel to slipeasily ofl' same and pre vent the dulling of the chisel. Below thebeveled portions said edges are straight edges which serve to guide thetool in making the upper and lower cuts for the depth of the hinge, andthe inner or left hand edge of the tool guide as shown has also astraight edge and serves to guide the tool in making a vertical cut forthe depth of the mortise. The gage B is also preferably provided with arearwardly extending arm I), seen in enlarged view in Fig. 1, which isperpendicular to the arm 6 and embraces the face of the door-jamb C orthat part of i The tool guide 6 as also the tool guide I)",

are adjustable in and out upon the said arms, and the slots containedtherein permit the adjustment of the arm of the gages B relatively toeach other. The inner opposite edges of the arms I) are straight edgesfor locating the position of the upper and lower sides of the hinge andconstitute tool guides for cutting the mortise at such points. They maybe beveled at their upper edges as are arms The inner face of the toolguide 6 9 also locates the width of the mortise for the hinge andconstitutes a guide for the tool employed to make such cut.

In operation the frame A may be laid upon the floorand the door-jambsecured to the outer parts thereof in any suitable manner, as by clampsif desired; the frame and door-jamb will then be erected in position inthe doorway as usual and trued up by means of the levels, the usualblocks being inserted if necessary for the purpose of holding it plumb.After the door-jamb has been secured the gages B may be adjusted tothe'position which it is desired the hinge shall have. The set screws 79may then be .screwed on the jamb. The arms 72 will then be at the sideof the jamb G and the arms I) at the face thereof. The set screws 1) maythen be loosened and the slides 19 adjusted so that tool guide Z2 willindicate the proper depth for the hinge when the said set screws will betightened. Slides Z2 will then be adjusted until the tool guide (2 shallindicate the proper width of the mortise for the hinge. -A chisel maythen be employed against the straight edges of arms o and tool guide 6to make the cuts in the face of the jamb for the hinge mortise, andsuitable chisels against the straight edges of arms 12 and tool guide 6to remove the said material to a proper depth. The tool guides 6 and bmay be held upon their supporting pins by set screws if desired.

While I have illustrated my invention as applied to an adjustabledoor-jamb setting frame in connection with which it is extremely useful,I do not regard it as limited in its application to such construction offrame, nor is it to be understood by reason of the particularity withwhich I have described the construction of my improved gage and themanner for permitting the adjust-ment of the various parts and securingthe same in position, that I regard my invention as necessarily limitedto these particular details, as equivalent means may be employed withoutdeparting from the spirit of the invention.
